, Claims.

My invention relates to a novel construction of header for use in the packing of roll roofing material and the like. It has been the practice heretofore to wrap the outer surface of a roll of 5 roofing material, such as tar paper, with a tough wrapping paper. This wrapping paper, however, is ordinarily not extended over the ends of the roll roofing material, but instead a header is applied to said ends. Headers heretofore have been in the nature of materials, such as muslin or canstrip of material.

It has been` found in practice that headers of the prior art were often damaged during transportaton. .Rolls of roofing material while being loaded or during ordinary handling would often become distorted in shape. Thus instead of the ends of the roll being circular in section, they often assume, an elliptical form. It is a common occurrence to have the header itself become ruptured due to this distortion with the result that the end of the roll will often become damaged. It is also common to insert within the core of the roll, a package of cement and nails which is to be used with that particular roll. When a header is ruptured, as stated above, these packages of cement and nails often fall out of the core of the roll roong material. Before a roll reaches its destination, it is thusoften badly damaged and does not contain the packages of cement and nails which should go with it.

It is my intention to eliminate these faults by a novel constructon of header which is of a knitted fabric, knitted in such a fashion as to have a high degree of elasticity. The fabric is of such a construction that it might readily be slipped over the end of the roll, different size rolls being accommodated by the same size header due to the elasticity of the fabric. While heretofore various size headers had to be made for Various size rolls, it is apparent that with an elastic header of my type the same header might be used for different size rolls within a certain range limitation. Also due to the elasticity of the material, it has been found in actual practice that my header lends itself to the shape of the roll regardless Whether it is cylindrical or elliptical, so that the likelihood (Cl. 20S- 59) of the header breaking due to handling and transportation is very much lessened.

Another object of my invention is'to provide an elastic header which might readily and quickly be applied tO the roll material, thus eliminating 5 waste time to enable speeding up plant production.

Another Object of my invention is to provide a header which will smoothly t the end of the roll without folds, tucks, or puckering, so that the 10 final job is smooth and Workmanlike in its appearance.

My invention is preferably applied as a header to roll roong material, but it is obvious that it has analogous uses asa header for rolls of print- 15 ing paper, or as a header for use with barrels, baskets and the like.

The preferred embodiment of my invention is shown in the drawing in which;

Fig. 1 is a perspective view of the end of a roll A20 of roofing material completely wrapped and having attached my novel header;

Fig. 2 is an enlarged elevational view, partly in section, of the end of a roll of roong material having attached thereto my header; 25

Fig. 3 is a plan view showing my header as it' appears when applied to the end of the roll roofing material;

Fig. 4 is an elevational View of the header made of a knitted fabric and the way it appears before 30 being `applied over thev endof the roll roofing material; and,

Fig. 5 is a sectional view taken through the plane 5 5 of Fig. 4.

As shown in Fig. 2 rolls of roofing material 1 35 Vare ordinarily wrapped in a tough wrapping paper, indicated as 4. This wrapping paper covers the outer surface of the cylindrical roll, but does not extend around the end of the roll. The end of the roll is protected by what is commonly 40 called a header. 'I'he header in my particular case is indicated by the character I, and it comprises a loosely knitted elastic fabric, as shown in Fig. 1. Adjacent edges of the fabric l at one end are sewed Or clipped together as indicated by the 45 sectional view of the Fig. 5. The other end of the knitted fabric 8 is left open so that it may be slipped over the end of a roll of roong material. It is absolutely essential that this knitted fabric be Woven in such a manner that it has a high 50 degree of elasticity lengthwise and Widthwise. Any known weave which will permit this elasticity might be used. Between the roll of roofing material 1 and the header l there is ordinarily placed an end disc 6 of circular shape to fit the contour 55 of the roll. This disc covers the hollow core of the roll. It has been the practice to insert within said core a package of cement and a package of nails to be used with that particular roll of roofing material. The function of the end disc is primarily to prevent the loss of the packages of cement and nails within the core of the roll roofing material during the' transportation of the same.

The overlapping edge 3 (Fig. 2) of the header fits over the marginal edge of the roll in a snug fashion due to the elasticity of the knitted fabric. In this manner any tucks or puckering of the material is eliminated. It is obvious that due to the elasticity of the knitted fabric it might be used for various size rolls Within a certain range limitation. The overlapping edge 3 of the header is attached to the wrapping paper 4 by a circumferential strip of adhesive paper 5.

In the application of my invention the roll of roong material 1 is presented to an operator completely wrapped in the outer wrapping paper 4, except for the outer ends of the roll. The operator then places a disc 6 and one of my elastic knitted headers, which has been slightly dampened with water, over the end of the roll roofing material, as shown in Fig. 2. This elastic knitted header when applied assumes the appearance shown in Fig. 3, wherein the threads of the fabrics emanate from the sewed ends 2-2 in the form of cords. This particular arrangement of fabric permits the threads of the fabric to adjust themselves readily to the contour of the roll and furthermore lends strength to the fabric header. With the knit extending in radial lines, as shown, a greater tensile strength is afforded the header as the natural strength of knit goods is in this direction. Also the concentration of cords or ribs at the center of they header affords greater strength at this point which reinforces the core portion of the roll. The attached edges 2 of the header are positioned over the core of the roong material outside of the end discs 6. The marginal edges of the wrapping paper are prepared with an adhesive so that the lapping edges 3 of the knitted header will adhere thereto. To permanently attach the lapping edges 3 to the wrapping material 4, an adhesive strip 5 is attached in lapping relationship over the knitted material 3 and the wrapping paper 4, as clearly indicated in Fig. 2. In such` manner the header is now completely attached to the roll of roofing material. When the elastic knitted fabric l dries, it shrinks slightly so as to give a close t on the end of the roll.

. 'I'he advantage of my invention is obvious, in so far as the elasticity of my header permits it to be applied to various size rolls. Also this elasticity permits the header to assume the shape of the roll which might become distorted due to shipping and loading. The accommodation of the header to different size and shapes of rolls is done without weakening the header construction itself.

It is apparent that known knitted materials of different weave might be used, but I do not intend to limit my invention to any particular weave in so far as the elastic characteristic of the weave is the controlling feature. It is not my intention to limit the invention to the preferred embodiment shown, but rather to cover all the equivalent structures as defined by the scope of the following claims:-

I claim as my invention:

' 1. A header for covering the ends of a roll of roofing material, comprising a loosely knitted fabric formed in the shape of a cap to fit over the end of the roll, said fabric being elastic in both lengthwise and Widthwise directions.

2. A header for covering the ends of a roll of roofing material or the like, comprising a loosely knitted fabric shaped as a bag, open at one end and fastened at the opposite end, said fabric being elastic in both lengthwise and widthwise directions so as to t snug over the end of a roll which has a larger circumference than the normal contracted circumference of the header fabric.

3. The combination with a roll of roofing material or the like having a hollow core, a circular end disc to cover the outer end surface of the roll, a loosely knitted fabric shaped as a bag, open at one end and sewed at the opposite end, said fabric being highly elastic so as to f'lt snug over the end of the roll, and the sewed portion of the bag extending substantially across the hollow core portion of the roll.

4. The combination with a roll of roofing material having a hollow core, a loosely knitted fabric shaped as a bag, open at one end and sewed at the oppositeend, said fabric being highly elastic so as to t over the end of the roll snug, and the sewed portion of the bag extending substantially across the hollow core vportion of the roll only, so that the knit extends as radial lines from the core of the roll.

5. The combination with a roll of roong material or the like having a hollow core, a circular end disc to cover the outer end surface of the roll, a loosely knitted fabric header shaped as a bag, open. at one end and sewed at the opposite end, said fabric being highly elastic so that its marginal edge snugly fits the end cylindrical surface'of the roll, and a strip of adhesive tape lapping the marginal edge of the fabric and the adjacent cylindrical surface of the roll.
